Can not store some stations using ATSSome station store with noise using ATS

Only limited FM stations can be received in Japan

Received very poor AM in USA

-no power with the batteries-didn't install the batteries properly

-power button is locked

-no power with the batteries-sleep timer is activated

-frequency of stations are too weak-there are interference near by your area

-FM frequency is 76~90MHz for Japan

-Because USA is using 10kHz step for AM

-replace the new batteries-according to "+" or "-" sign to install the batteries again-press [ ] button to unlocked

-replace the batteries

-turn on the radio again

-search the station manually- low down the antenna or move to other location and try again

-turn the radio off and long press on the [FM SET] button，short press [FM SET] button again to select 76~108MHz

-turn off the radio press the [9/10kHz] button to select 10kHz

ATS( Auto Tuning Storage) on FM, MW, LW, SW band1. Turn on the radio, and fully extend the antenna. 2. Short press [FM] button to Select FM band. 3. Long press on [FM] button until frequency number is running on the display. All the available stations will be stored in the memory automatically. It will stop when it is done. 4. Then use the [TUNING] knob to tune around for those stored stations.

STORING FREQUENCIES INTO MEMORY 1. Turn on your radio, and tune into your favorite station.2. Short press [M] button, with the memory address is flashing in the display, press [M] button again to confirm.

Special note: There are mode A & mode B for ATS in SW.Mode A : Auto-searching & storing all the radio stations within all meter bands.Mode B: Auto-searching & storing all the radio stations within present meter band only.

Special note: During ATS processing in FM / MW / LW & SW with mode A, pre-stored radio stations would be deleted & covered automatically by the new searched stations. If ATS is interrupted or being turned off during process, for those radio stations without deleted & covered by ATS would still be kept. With ATS mode B in SW, those existing memories will not be deleted & covered; all the newly found radio stations would be stored in the blank memory addresses.

LISTEN TO STATIONS IN THE MEMORY1. Turn on the radio, press and release the [SCAN MODE] button with notice that the PRESET show in the display's upper right corner.2. Turn the [TUNING] knob to select stored stations.

Caution: Don't install external FM/ AM antennain the frequent thunder area.

The external antenna socket is used to improve shortwaveor FM performance.

1. If no battery has been installed inside for long time, clock of radio would stop to work. However, pre-stored frequencies are still kept. Clock would work again after new batteries being re-installed inside.2. When the battery power is low, the " " symbol in the display will flash to alert you for changing new batteries. Besides it will turn off automatically when the power is gone.3. Mix using the used & new batteries would cause damage of radio and also display the capacity of power incorrectly.4.
